Would be useful to view at a glance the status of the system and arm/disarm on the home screen without entering the app (could be an overlay on the app logo or constant status in the notification bar, similar to a weather app).

The IfTTT app allows you to change the status, but requires 2 widgets for both arm/disarm. If you use IfTTT across multiple applications, you can understand how cluttered your device gets with widgets, aside from the applications they’re intended to manipulate.

Would be very useful when sharing a system among family members who are arriving/departing the home at different times, to be able to monitor/change the status without opening the app.
